Removable Automotive LIDAR Data Collection POD

ABSTRACT

A vehicle agnostic removable pod can be mounted on a vehicle using one or more legs of a pod mount. The removable pod can collect and time stamp a variety of environmental data as well as vehicle data. For example, environmental data can be collected using a sensor suite which can include an IMU, 3D positioning sensor, one or more cameras, and/or a LIDAR unit. As another example, vehicle data can be collected via a CAN bus attached to the vehicle. Environmental data and/or vehicle data can be time stamped and transmitted to a remote server for further processing by a computing device.

BACKGROUND

As computing and vehicular technologies continue to evolve, autonomy-related features have become more powerful and widely available, and capable of controlling vehicles in a wider variety of circumstances. For automobiles, for example, the automotive industry has generally adopted SAE International standard J3016, which designates 6 levels of autonomy. A vehicle with no autonomy is designated as Level 0. With Level 1 autonomy, a vehicle controls steering or speed (but not both), leaving the operator to perform most vehicle functions. With Level 2 autonomy, a vehicle is capable of controlling steering, speed, and braking in limited circumstances (e.g., while traveling along a highway), but the operator is still required to remain alert and be ready to take over operation at any instant, as well as to handle any maneuvers such as changing lanes or turning. Starting with Level 3 autonomy, a vehicle can manage most operating variables, including monitoring the surrounding environment, but an operator is still required to remain alert and take over whenever a scenario the vehicle is unable to handle is encountered. Level 4 autonomy provides an ability to operate without operator input, but only under certain conditions such as only in certain types of roads (e.g., highways) or only in certain geographic areas (e.g., a geofenced metropolitan area which has been adequately mapped). Finally, Level 5 autonomy represents that a vehicle is capable of operating without operator input under all conditions.

A fundamental challenge to any autonomy-related technology relates to collecting and interpreting information about a vehicle's surrounding environment, along with planning and executing commands to appropriately control vehicle motion to safely navigate the vehicle through its current environment. Therefore, continuing efforts are being made to improve each of these aspects, and by doing so autonomous vehicles increasingly are able to safely and reliably operate in increasingly complex environments and accommodate both expected and unexpected interactions within an environment.

SUMMARY

Techniques are described herein that enable a method and apparatus that include a vehicle agnostic removable pod equipped with a sensor suite and a computing device for collecting and time stamping data about a vehicle's surrounding environment as well as data about the vehicle itself. The sensor suite of a removable pod (also referred to herein as a “pod”) can collect a variety of environmental data utilizing a variety of sensors including an Inertial Measurement Unit (“IMU”), a three dimension (“3D”) positioning sensor (e.g., a Global Positioning System (“GPS”)), one or more cameras, a Light Detection and Ranging (“LIDAR”) unit, etc. The removable pod can also connect to the vehicle for direct data collection from the car in additional to data collected by sensors integrated into the removable pod. For example, the removable pod can connect to a vehicle Controller Area Network (“CAN”) bus, for example by connecting to a vehicle's on board diagnostics (“OBD”) port (e.g., an OBDII port), to gain access to a variety of vehicle data such as vehicle speed data, braking data, steering control data, etc. Additionally or alternatively, the removable pod can be powered by the vehicle. For example, a removable pod can be powered by a DC connector in the vehicle (e.g., a 12 volt vehicle receptacle), a USB port in the vehicle, or various other electrical connections within the vehicle, such as a vehicle taillight, etc. In several implementations, mounting removable pods on a variety of vehicles can create a greater diversity of environmental data measurements compared to collecting environmental data using a single vehicle.

A computing device connected to the removable pod can record environmental data collected by the sensor suite as well as vehicle data from a CAN bus. In a variety of implementations, the computing device can time stamp the data as it is collected from the environment using the sensor suite integrated in the removable pod and/or directly as it is collected from the vehicle (e.g., collected vehicle data from the vehicle CAN bus). Additionally or alternatively, a sensor can provide its own time stamp (e.g., a LIDAR unit can generate its own time stamps for data it collects). In many implementations, the computing device can combine the environmental data, the vehicle data, as well as various predefined sets of data such as known information about a specific vehicle (e.g., known information about a vehicle's color, make, model, etc. can be supplied by a user when mounting the removable pod on a vehicle) with the corresponding time stamps to generate a single data structure. In some such implementations, these data structures can be uploaded to a remote server (i.e., upload the data to the cloud) for further remote processing. Processing of the data collected using the sensor suite of the removable pod (i.e., environmental data) and/or data collected directly from the vehicle (i.e., vehicle data) with corresponding time stamps can be performed in real time, near real time, and/or the data can be stored and processed at a later time. In some implementations, the data collected by the removable pod can be combined and processed with additional data collected from other sources, for example from one or more additional removable pods. In other words, data collected from two vehicles each mounted with a removable pod in a similar location at the same time can be combined into a single data set.

In many implementations, the removable pods can be vehicle agnostic. In other words, removable pods can be mounted on many (and for some removable pod configurations, any) vehicle type. For example, removable pods can be mounted on cars, trucks, motorcycles, sports utility vehicles, vans, mopeds, tractor trailers, busses, motorized scooters, etc. Additionally or alternatively, removable pods can be mounted on variations of vehicles within a vehicle type. For example, car manufactures make a wide variety of types of cars, and the removable pod can be mounted on many cars regardless of their make and model. By allowing the removable pod to be vehicle agnostic, a richer set of diverse data may be collected from various automobile perspectives. Several vehicle agnostic removable pods mounted on various vehicles can quickly collect a large amount of data. In other words, the data collection can scale very quickly by, for example, going to a new location and placing removable pods of a group of rented cars.

In some implementations, multiple removable pods can be mounted on a single vehicle. For example, two pods can be mounted on a car towing a trailer (i.e., one removable pod can be mounted on the car and a second removable pod can be mounted on the trailer). At times the car and the trailer will move in different directions (e.g., when the car is backing up, etc.) and data from both the car and the trailer can be useful for further analysis. In implementations, the pod attached to the car and the pod attached to the trailer can collect data simultaneously. Multiple pods attached to a single vehicle can connect to the same computing device to collect and store data. Additionally or alternatively, multiple pods attached to a single vehicle can each interface with their own computing device to collect data and the data from the multiple removable pods can be aggregated together once the computing devices uploads the various time stamped data to the cloud or other storage media.

To analyze sensor data collected from the removable pods, it can be important to know the position of the removable pod on the vehicle. In many implementations, mounting a pod includes determining the position of the pod and/or determining if the pod is in a valid position. A valid position as used herein means the removable pod has been mounted on a vehicle such that sensors in the removable pod are aligned in a position where the sensors can collect data from a known predefined perspective. In some implementations, a user interface on the computing device can guide a user through positioning the removable pod on the vehicle. For example, if the desired location of the pod is the center of the roof of a car, a user interface can guide a user in finding the center of the roof. In many implementations, the sensor suite within the removable pod can capture data while a user is positioning the pod. For example, one or more sensors within the removable pod can take measurements of the vehicle. In a variety of implementations, a user can provide identifying information about the vehicle (e.g., a make, model, year, etc. of a car) and measurements of the vehicle can be determined from a database either stored locally on the computing device and/or accessed on a remote server in order to properly identify the optimum predefined position for data collection of that particular vehicle. Additionally or alternatively, vehicle measurements can be determined from both user provided identifying information and measurements of a vehicle taken using one or more sensors in a pod. Moreover, once a user has mounted the removable pod, the sensor suite can capture additional data to confirm the valid placement of the pod for the user.

A removable pod can be attached to a vehicle using one or more adjustable pod mounts (e.g., a tripod style three pod mount configuration) that allows the sensor suite in the removable pod to be aligned to the valid position regardless of the shape of the vehicle. In other words, one or more legs of the pod mount can be adjusted such that the sensors in the pod are positioned to collect data for variably shaped vehicles. For example, the roof of vehicle A can have a different curvature compared to the roof of vehicle B. The adjustable mount can align the removable pod on both vehicle A and vehicle B by adjusting one or more legs of the tripod mount to account for the curvature of the particular vehicle roof. Legs of the tripod mount can attach to a vehicle in a variety of ways including suction cups, magnets, etc. In some implementations, the pod can be centered on the top of a vehicle (e.g., centered on the roof of a car, centered on the roof of a truck, etc.). In other implementations, the pod can be attached to the front of a vehicle (e.g., positioned on the front of the roof of a car, positioned on the front of a motorcycle, etc.). In some implementations, the pod can be attached to a vehicle in a position to increase the field of view of the pod sensors. In other words, the position of the pod can reduce one or more portions of the vehicle that obstruct the field of view of the sensors, such as positioning the removable pod at the highest point on a vehicle to increase the field of view of the environment for LIDAR unit data collection.

Removable pods can be mounted in some implementations on autonomous vehicles to supplement the sensors available to the autonomous vehicle. In such implementations, a removable pod may not contain the full variety and/or number of sensors found in an autonomous vehicle. Additionally or alternatively, removable pods can be mounted on non-autonomous vehicles. In some implementations, removable pods mounted on non-autonomous vehicles can collect data which can be processed remotely and used in training the control systems of autonomous vehicles. In some implementations several non-autonomous vehicles having a mounted removable pod and/or several autonomous vehicles can drive in the same area to simultaneously collect data. Furthermore, in implementations, a variety of multiple non-autonomous vehicles can be used simultaneously to increase the diversity of the data collected. For example, the removable pods can be mounted on several different makes, models, and types of vehicles.

Data collection by a removable pod on a vehicle moving throughout a mapping area concurrently traversed by autonomous vehicles may be beneficial to supplement existing mapping data. For example, data collected from a pod on a vehicle at a known location and time may be used in automatic labeling of data collected from an autonomous vehicle. For example, in some implementations, the removable pod may collect environmental data through a suite of sensors in the vehicle including data available in the CAN. Once this data collected using a removable pod from a non-autonomous vehicle (i.e., non-AV data) is correlated in time and place with the autonomous vehicle, systems may be utilized to automatically label autonomous vehicle collected data related to the non-autonomous vehicle. Such data collection and labeling may extend as well to sensor data obtained by and external to the non-autonomous vehicle. For example, labeled data can be utilized to aid in labeling objects in the environment that are visible to the non-autonomous vehicle removable pod sensor suite but are occluded from the view of the autonomous vehicle sensor suite. In other words, the field of view of the autonomous vehicle can be extended by mapping labeled data collected by a removable pod mounted on a non-autonomous vehicle to a temporally and/or physically located autonomous vehicle.

Data collection by a removable hardware pod as disclosed herein can quickly generate large amounts of data. Furthermore, by mounting removable hardware pods on varying types of vehicles, varying removable pod positions, varying pod hardware, etc., a greater diversity of data can be collected. This collected data can be used in training a machine learning model, and the large diversity of data can reduce overfitting the machine learning model to the training data. Additionally or alternatively, removable hardware pods can reduce the cost associated with data collection by allowing virtually any vehicle to be used in data collection without specific customization of the vehicle being necessary.

The above description is provided as an overview of various implementations disclosed herein. Those various implementations, as well as additional implementations, are described in more detail herein.

In some versions of those implementations, the method further includes determining an aggregation of the stored time stamped instances of environmental data and the time stamped instances of vehicle data for each removable pod in the plurality of removable pods. In some versions of those implementations, determining an aggregation of the stored time stamped instances of environmental data and the time stamped instances of vehicle data for each removable pod further includes determining an aggregation of the stored time stamped instances of environmental data and the time stamped instances of vehicle data for each removable pod in the plurality of removable pods with an external data source.

DETAILED DESCRIPTION

Referring to FIG. 1 , a block diagram of an example environment is illustrated in which implements disclosed herein may be implemented. Example environment 100 in FIG. 1 includes external removable pod hardware 102 and vehicle cabin removable pod hardware 116.

In a variety of implementations, one or more components of external removable pod hardware 102 can be contained in hardware housing 206 as illustrated in FIG. 2 .

Vehicle cabin removable pod hardware 116 can be separate from the mountable pod hardware. In some implementations, vehicle cabin removable pod hardware 116 can include USB adapters 118, 120, computing device 122, AC adapter 124, 12V vehicle receptacle 126, OBDII port 128, etc. Computing device 122 can include a variety of devices including a laptop computing device, a tablet computing device, a cellular telephone computing device, etc.

The vehicle itself can power external removable pod hardware 102 and/or computing device 122. In some such implementations, 12V vehicle receptacle 126 can connect to PCB 110 to provide power to external removable pod hardware 102. Additionally or alternatively, 12V vehicle receptacle 126 can provide power to AC adapter 124. In some such implementations, AC adapter 124 can provide power to computing device 122. Additionally or alternatively, computing device 122 can include one or more USB ports, each of which can connect to one or more USB adapters such as USB adapter 118, 120.

Environmental data collected by one or more cameras 106/108 for example, can be transmitted via a USB adapter to computing device 122. Additionally or alternatively, one or more cameras can receive power using a USB adapter. Furthermore, computing device 122 can transmit one or more control signals to one or more cameras utilizing connections made by USB adapters. For example, wide field of view camera 106 can transmit environmental data to computing device 122, receive command signals from computing device 122, and/or be powered utilizing USB adapter 118. Similarly, narrow field of view camera 108 can transmit environmental data to computing device 122, receive command signals from computing device 122, and/or be powered utilizing USB adapter 120. In some implementations, multiple cameras can connect to computing device 112 via a single USB adapter. Additionally or alternatively, in many implementations any of a variety of cameras can be used including the aforementioned wide field of view camera 106 and narrow field of view camera 108 as well as a light field camera, a thermal imaging camera, etc. In many implementations, one or more cameras can connect directly to PCB 110 (not illustrated).

Computing device 122 can connect to PCB 110 in external removable pod hardware 102 via an Ethernet connection. In many implementations, an Ethernet connection can be a wired connection. Additionally or alternatively, an Ethernet connection can be a wireless connection. Computing device 122 can transmit information to PCB 110 as well as receive environmental data collected by a variety of sensors in the external removable hardware pod 102 via the Ethernet connection. In some implementations, 3D positioning sensors 112 can be integrated directly into PCB 110. In other implementations, 3D positioning sensors 112 can be separate and connect with PCB 110 (not illustrated).

PCB 110 can provide power (for example 12V) to a variety of sensors including 3D positioning sensors 112, LIDAR unit 104, IMU 114, wide field of view camera 106 (not illustrated), narrow field of view camera 108 (not illustrated), etc. In many implementations, PCB 110 can synchronize timing with LIDAR unit 104 via a serial pulse per second (“PPS”) connection, an Ethernet connection, and/or additional connections. Additionally or alternatively, PCB 110 and LIDAR unit 104 can transmit and receive data via an Ethernet connection. For example, environmental data collected by LIDAR unit 104 can be transmitted to PCB 110 via an Ethernet connection. In various implementations, PCB 110 can transmit and receive information with IMU 114. In many implementations, PCB 110 can interface with vehicle data ports, such as OBDII port 128, to additionally collect a variety of corresponding vehicle data. Additionally or alternatively, computing device 122 can interface with a vehicle data port including OBDII port 128 to collect a variety of additional vehicle data (not pictured) such as information collected from the additional vehicle's CAN bus. Additional vehicle data in accordance with many implementations can include: vehicle speed data, braking data, steering control data, etc.

In a variety of implementations, environmental data and/or vehicle data can be appended with a time stamp by PCB 110, computing device 122, and/or individual sensors (e.g., LIDAR units can generate their own time stamps). Additionally or alternatively, time stamped environmental and/or time stamped vehicle data can be combined and uploaded to the cloud using computing device 122 in conjunction with known communication pathways and hardware. In some such implementations, the removable pod can combine time stamped environmental and time stamped vehicle data by creating an instance of data at each time step (i.e., each instance of data can include environmental data at a specific time stamp (if any) as well as vehicle data at the same specific time stamp (if any)).

FIG. 2 illustrates an image 200 of a removable pod in accordance with implementations disclosed herein. Removable pod 202 can include a variety of elements such as one or more sensors 204, hardware housing 206, removable pod mount(s) 208, etc. One or more sensors 204 which can be utilized in removable pod 202 are illustrated in FIG. 1 .

In a variety of implementations, a LIDAR unit can be the highest point on a removable pod 202. Hardware housing 206 can protect various portions of removable pod 202 from weather elements such as rain, snow, wind, hot temperatures, cold temperatures, etc. A variety of shapes of hardware housing can be utilized in removable pod 202 in addition or alternatively to hardware housing 206 as illustrated in FIG. 2 . For example, hardware housing 206 can include two or more housing units to house separate portions of the removable pod 202 as well as a different shaped hardware housing 206.

In a variety of implementations, removable pod mount(s) 208 can attach removable pod 202 to a vehicle. Removable pod mount(s) 208 can be adjusted such that sensors within a removable pod 202 can collect data from a preferred defined position and/or location. For example, removable pod mount(s) 208 can be adjusted to compensate for different curvatures between different vehicles. Removable pod mount(s) 208 can attach removable pod 202 to a vehicle in a variety of ways including: suction cups, magnets, adhesives (e.g., glue, tape), etc. In some implementations, removable pod mount(s) 208 can be a single mount. Varying number of mounts can be included in removable pod 202 in accordance with various implementations. For example, removable pod 202 can include two removable pod mounts 208, three removable pod mounts 208, four removable pod mounts 208, etc. In many implementations, three removable pod mounts 208 can be arranged in a tripod style configuration.

FIG. 3 illustrates an image of a removable pod mounted on a vehicle in accordance with implementations disclosed herein. Combined automobile and pod 300 includes removable pod 202 mounted atop a vehicle 302 in a predefined preferred position. In a variety of implementations, removable pod 202 is vehicle agnostic and can be mounted on a variety of vehicles 302 including: cars, trucks, motorcycles, sports utility vehicles, vans, mopeds, tractor trailers, busses, motorized scooters, etc. In some implementations, components linked with removable pod 202 can be inside vehicle 302. For example, vehicle cabin removable pod hardware 116 (as illustrated in FIG. 1 ) can be inside the vehicle. As a further example, vehicle cabin removable pod hardware 116 can be inside a car, sports utility vehicle, truck, bus, etc. In some such examples, a laptop computer can be utilized as computing device 122 in removable pod hardware 116, and the laptop computer can be stored inside the vehicle. In other implementations, a vehicle can lack an enclosed interior and vehicle cabin removable pod hardware can be stored “in” the vehicle in additional ways. For example, a motorcycle can utilize a cellular telephone computing device as computing device 122 in removable pod hardware 116. In some such examples, the motorcycle rider can carry the cellular telephone in a pocket. In implementations, the vehicle cabin removable pod hardware 116 can be combined with the external removable pod hardware. Alternatively, various portions of the external removable pod hardware 102 can be combine with selected portions of the vehicle cabin removable pod hardware 116.

In many implementations, several removable pods 202 can be mounted to vehicle 302 to increase the density of data collection. For example, a car can have a removable pod 202 mounted to its front right side and an additional removable pod 202 can be mounted to its front left side. As another example, a vehicle pulling a trailer can have a removable pod 202 mounted to the vehicle and a second removable pod 202 mounted to the trailer to capture, for example, additional data when the trailer moves in a different direction from the vehicle. As a further example, a bus can have three removable pods 202 mounted along the top to capture additional environmental data a single removable pod 202 could potentially miss because of the larger size of a bus when compared to a smaller vehicle such as a car. For example, line of sight perspectives of a pod on a larger vehicle could be restricted or even blocked due to the irregular shape of the vehicle, position of the pod or other reasons. Multiple pods on a vehicle may provide the ability to collect data from different perspectives, positions or obtain line of sight data not previously recordable. In some implementations, the removable pod is not connected to the vehicle control system of the vehicle to which the pod is mounted upon. In other words, the removable pod collects data and does not generate and/or send signals to control the vehicle.

Referring to FIG. 4 , an example process 400 for practicing selected aspects of the present disclosure, in accordance with various implementations is disclosed. For convenience, the operations of the flowchart are described with reference to a system that performs the operations. This system may include various components of various computer devices, including those described in FIG. 1 and/or FIG. 8 . Moreover, while operations of process 400 are shown in a particular order, this is not meant to be limiting. One or more operations, elements, and/or steps may be reordered, omitted, and/or added.

At block 402, the system collects environmental data using removable pod hardware. In many implementations, environmental data includes a variety of information collected about a vehicle's surrounding environment. Environmental data can be collected by one or more sensors in the removable pod including an IMU, a 3D positioning sensor (such as GPS), one or more cameras, a LIDAR unit, etc. In many implementations, environmental data can be collected by one or more additional sensors included within the vehicle. For example, environmental data can include information collected by a rear backup camera in a vehicle.

At block 404, the system may also collect various additional vehicle data. In many implementations, vehicle data can be collected by one or more processors within the removable pod via a CAN bus which can, for example, be connected to an OBDII port in a vehicle. In various implementations, vehicle data can include information relating to the control of a vehicle including vehicle speed data, vehicle braking data, vehicle steering control data, etc.

At block 406, the system records collected environmental data and/or collected vehicle data can be recorded using the computing device. In a variety of implementations, the computing device, such as computing device 112 (as illustrated in FIG. 2 ) can be stored inside a vehicle. For example, a laptop computer can be utilized as the computing device and in some implementations can be stored inside a car. Alternatively or in addition thereto, recordation of the data may occur on a separate storage device operatively connected to the hardware 116, incorporated with hardware 116, or transmitted for recording remotely. At block 408, the system determines time stamps for instances of collected environmental and/or vehicle data. In many implementations, a time stamp can be associated with data using the computing device. In other implementations, sensors (e.g., LIDAR units) can provide their own time stamp which can be synched with computing device time stamps (if necessary). Additionally or alternatively, a PCB within removable pod hardware (such as PCB 110 as illustrated in FIG. 1 ) can be time synched with the computing device (such as computing device 122 as illustrated in FIG. 1 ). The PCB can provide time stamps for data collected by one or more sensors in the removable pod, and transmit environmental data with an associated time stamp to the computing device.

At block 410, the system transmits time stamped environmental data and/or time stamped vehicle data to a remote server for additional processing. In many implementations, additional processing can combine time stamped environmental and/or time stamped vehicle data from several removable pods. Additionally or alternatively, time stamped environmental data and/or time stamped vehicle data can be utilized to generate training data for a machine learning model such as a machine learning model utilized to generate control signals for an autonomous vehicle. In other implementations, additional processing can occur on the computing device (such as computing device 122 as illustrated in FIG. 1 ) prior to transmitting data to a remote server. Additional processing can occur in real time, near real time, and/or data can be stored and processed at later time.

FIG. 5 illustrates an example combined vehicle and pod 500 of measurements of a removable pod mounted on a vehicle in accordance with implementations disclosed herein. FIG. 6 illustrates another example combined vehicle and pod 600 of measurements of a removable pod mounted on a vehicle. Images 500 and 600 include removable pod 202 and vehicle 302 similar to a removable pod and vehicle described in one or more of FIGS. 1-3 . Image 500 includes a view of a removable pod mounted to a vehicle with respect to an X axis and a Z axis 516 where the X axis is in a direction substantially perpendicular to the Z axis. Image 600 illustrates a view of a removable pod mounted to a vehicle with respect to an X axis and a Y axis 608 where the X axis is substantially perpendicular to the Y axis. In many implementations, positions of a removable pod mounted on a vehicle as well as dimensions of a vehicle can be determined by measurements in an X axis, a Y axis, and a Z axis.

In many implementations, vehicle measurements can be utilized to determine the position of a removable pod mounted on a vehicle, and for example, if a pod is mounted in a correct position. In many implementations, a removable pod can be mounted in many positions. For example, a removable pod can be placed in many locations on the top of a car including the front center, the front left, the front right, the center of the middle of the car, etc.

In many implementations, a variety of measurements can be taken of the position of removable pod 202 mounted on vehicle 302 as well as measurements of the dimensions of vehicle 302. In various implementations, one or more sensors in a mounted removable pod can determine various measurements. Additionally or alternatively, vehicle measurements can be determined from a database of known vehicle information by a user providing the removable pod with identifying vehicle information (i.e., vehicle make, vehicle model, vehicle year, etc.). Furthermore, a human can manually take measurements of a vehicle and/or removable pod mounted on a vehicle. In many implementations, vehicle and/or removable pod measurements can be determined by a combination of measurements from one or more sensors in a removable pod, known vehicle measurements of various vehicles from a database, and/or manual measurements by a user.

In various implementations, the position of a mounted removable pod can be determined in three dimensions by measuring pod height 502 (Z axis), pod position X 504 (X axis) and pod position Y 604 (Y axis) as illustrated in FIGS. 5 and 6 . Additionally or alternatively, vehicle measurements can be determined in three dimensions by measuring vehicle height 506 (Z axis), vehicle length 508 (X axis), and vehicle width 602 (Y axis). In many implementations, the front wheel position can be determined by measuring axel height 510 (Z axis) and front axle overhang 512 (X axis). Similarly, rear wheel position can be determined by measuring axel height 510 (Z axis) and rear axle overhang 514 (Y axis).

In a variety of implementations, different types of vehicles can be measured by a variety of sets of measurements. For example, the set of measurements for a truck can be different from the set of measurements for a motorized scooter. Additionally or alternatively, a variety of measurements can be taken when multiple removable pods are mounted on the same vehicle.

Referring to FIG. 7 , an example process 700 can position a removable pod on a vehicle in accordance with various implementations is disclosed. For convenience, the operations of the flowchart are described with reference to a system that performs the operations. This system may include various components of various computer systems, including those described in FIG. 1 and/or FIG. 8 . Moreover, while operations of process 700 are shown in a particular order, this is not meant to be limiting. One or more operations, elements, and/or steps may be reordered, omitted, and/or added.

At block 702, the system attaches a removable pod to a vehicle using one or more pod mount(s) similar to pod mount 208 illustrated in FIG. 2 . In many implementations, the position of the removable pod is within the leveling capabilities of the pod mount(s). In other words, a removable pod can be mounted on a surface that is not flat (e.g., the curved hood of a car) such that adjustable pod mount(s) can position sensors within the removable pod in a valid location. In many implementations, removable pod mount(s) can attach a removable pod to a vehicle utilizing suction cups, magnets, adhesives, etc. Additionally or alternatively, a removable pod can be positioned as close to the front of a vehicle that is within the leveling capabilities of the pod mount(s). In other implementations, a removable pod can be placed in any position where pod mount(s) can position the sensor suite of the removable pod in a position to collect data.

At block 704, the system adjusts the position of the removable pod using the pod mount(s). In a variety of implementations, the height of leg(s) of pod mount(s) can be adjusted such that the sensor suite in the removable pod can collect data. Adjusting the height of a leg of a pod mount can increase or decrease the height of a pod mount. Additionally or alternatively, the height of individual legs of pod mounts can each be adjusted independently for a removable pods with multiple pod mounts.

At block 706, the system determines vehicle measurements and/or pod location measurements using one or more sensors in the removable pod. For example, 3D positioning sensors (such as GPS), cameras, etc., can gather vehicle dimension measurements and/or removable pod location measurements.

At block 708, the system determines the current position of the removable pod. As described with respect to FIGS. 5 and 6 , the position of a removable pod can be determined using a variety of measurements. In many implementations, a removable pod can utilize 3D positioning sensors (such as GPS), cameras, etc. and known information about vehicle measurements (e.g., manually measured vehicle measurements, vehicle measurements from known information about the specific vehicle, vehicle measurements taken using one or more sensors of the removable pod, etc.) to determine the positioning of a removable pod mounted on a vehicle. In a variety of implementations, the determined position of the removable pod can vary from the actual position of the removable pod. For example, a determined position of a mounted removable pod can vary by 10 cm in any direction and still provide accurate information. Additionally or alternatively, the determined position of a removable pod and the actual position of a removable pod can vary by additional increments such as twenty cm, fifteen cm, five cm, one cm, etc. in accordance with various implementations.

At block 710, the system determines if the removable pod is positioned in a valid location. As described herein, a removable pod can have multiple valid positions on a vehicle. If the system determines the removable pod is in a valid position, process 700 ends. Additionally or alternatively, if the removable pod is not in a valid position, the removable pod can be reattached in accordance with block 702 to the vehicle using one or more pod mount(s) and blocks 704, 706, 708, 710 can repeat until the removable pod is mounted in a valid position.
